They were both on their way to the businessman's house in a car when a SUV, bearing a Haryana registration number intercepted their vehicle. Four men with covered faces were inside.

Two of them got down, broke the windowpane on the driver's side of the businessman's car and took the car keys at gunpoint, the police said. Later, they opened the car's trunk and took the bag containing Rs 35 lakh in cash.

Deputy Commissioner of Police (Northwest) Aslam Khan said that an insider's job was suspected, since the accused were aware that the cash was being transported in the car.

'The police are probing whether any employees of the businessman were involved. They are also questioning the driver since he was hired just a month and a half ago.
